CVE-2024-46708 is a vulnerability identified in the Linux kernel specifically related to the pin control (pinctrl) subsystem for Qualcomm hardware, particularly the x1e80100 platform. The issue stems from an erroneous offset value (0x100000) applied to special pin offsets within the pinctrl driver. This incorrect offset causes the system to crash when attempting to set pin states, and it also prevents the intended pin state changes from taking effect properly. The vulnerability impacts the kernel's ability to correctly manage hardware pin configurations, which are critical for controlling various hardware functions on embedded and mobile devices using Qualcomm chipsets. The fix involves removing this erroneous offset to ensure stable and correct pin state management. Although no known exploits are currently reported in the wild, the vulnerability could lead to system instability or denial of service conditions on affected devices if exploited. The affected versions are specific commits identified by their hashes, indicating this is a recent and targeted fix in the Linux kernel source code. No CVSS score has been assigned yet, and no detailed exploit code or attack vectors have been published at this time.

For European organizations, the impact of CVE-2024-46708 depends largely on their use of Linux-based systems running on Qualcomm hardware, particularly embedded systems, IoT devices, or mobile infrastructure that rely on the affected pinctrl driver. The vulnerability could cause system crashes or failures in hardware control, potentially disrupting critical operations in environments such as telecommunications, industrial automation, or mobile network infrastructure. This could lead to downtime, reduced availability of services, and increased maintenance costs. While the vulnerability does not appear to allow direct code execution or privilege escalation, the denial of service or instability it causes could be exploited by attackers to degrade service reliability or cause operational interruptions. European organizations with embedded Linux devices in sectors like manufacturing, automotive, or telecommunications should be particularly vigilant. The absence of known exploits reduces immediate risk, but the potential for impact on availability and operational continuity remains significant.

Organizations should promptly apply the Linux kernel patches that remove the erroneous 0x100000 offset in the Qualcomm pinctrl driver once they become available in their distribution or vendor kernel updates. For embedded and IoT devices, firmware updates incorporating this fix should be prioritized. Additionally, organizations should audit their device inventory to identify systems running affected Linux kernel versions on Qualcomm hardware. Implementing robust monitoring for system crashes or unusual hardware behavior can help detect exploitation attempts. Where possible, isolating critical embedded systems from untrusted networks can reduce exposure. For development teams, reviewing custom kernel builds or patches for similar offset misconfigurations is advisable. Finally, maintaining a rapid patch management process for kernel updates and coordinating with hardware vendors for timely firmware updates will help mitigate this vulnerability effectively.
